示例1: it

    it("should subscribe to the wrapper asynchronously", () => {
      var called = false;
      ObservableWrapper.subscribe(emitter, (value) => { called = true; });

      ObservableWrapper.callNext(emitter, 99);
      expect(called).toBe(false);
    });

示例2: inject

       inject([AsyncTestCompleter], (async) => {
         // Each subscriber fires a microtask outside the Angular zone. The test
         // then verifies that those microtasks do not cause additional digests.

         var turnStart = false;
         ObservableWrapper.subscribe(_zone.onTurnStart, (_) => {
           if (turnStart) throw 'Should not call this more than once';
           _log.add('onTurnStart');
           microTask(() => {});
           turnStart = true;
         });

         var turnDone = false;
         ObservableWrapper.subscribe(_zone.onTurnDone, (_) => {
           if (turnDone) throw 'Should not call this more than once';
           _log.add('onTurnDone');
           microTask(() => {});

         var eventDone = false;

           eventDone = true;
         });

         macroTask(() => { _zone.run(_log.fn('run')); });

         macroTask(() => {
           expect(_log.result()).toEqual('onTurnStart; run; onTurnDone; onEventDone');
           async.done();
